6.2. Parameter settings MP-888
– flow controller 1.5…35 l/min
Each unit requires a different programme setting. For each model is a programme defined that not
every parameter must be set manually. In this program the model specific settings are saved.
Model:
TT-188 Program: P79
Function Factory adjusted Description
P1 Maximum temperature 150.0°C / 302.0°F
(0.0...400.0°C)
(32.0...752.0°F)
If the maximum temperature
exceeds, the heating and cooling are
inactive and the maximum
temperature LED lights up on the
controller.
P2 Temperature deviation
control
(Deviation between set
and actual temperature) 5.0°C / 9.0°F
(0…20.0°C)
(0…36.0°F)
The limit determines the maximum
deviation from the nominal value,
which is still tolerated. If the actual
temperature outside the set point
window the alarm will sound and the
Temperature deviation control LED
lights. If the restart lock (P24) is
turned on, the temperature deviation
control is active only when it reaches
the set temperature. A set point
changes the start-up lock again.
P3 Flow measurement
function 0: Manual
1: Automatic
If the automatic flow measurement is
enabled, after 20s the measured flow
is stored and monitoring is enabled.
The green LED lights up.
P4 Alarm value flow 8.0 L
(0.1…999.9 L)
(P3) set to manual
Alarm is triggered when the set value
is exceeded.
P20 Temperature unit 1: °C
2: °F
Change the temperature unit
When the unit started the selected
unit will be indicated for a short time.
P23 Analog input 1: Voltage 0-10V
2: Current 0-20 mA
3: Current 4-20 mA
Analog input for setpoint selection.
0-10 V
(switching threshold <0.1V)
0-20 mA
(switching threshold <0.5mA)
4-20 mA
(switching threshold <0.1mA)
P27 Temperature
at 0 V INPUT 0.0°C / 32°F
(-50.0...399.9°C)
(-58.0...751.8°F)
Lower scaling point of the voltage
analog input
0 V corresponds to 0°C
P28 Temperature
at 0 V INPUT 400.0°C / 752°F
(-
49.9…400.0°C)
(-
57.8…752.0°F)
Upper scaling point of the voltage
analog input
10 V corresponds to 400°C
P29 Temperature
at 0/4 mA INPUT 0.0°C / 32°F
(-50.0...399.9°C)
(-58.0...751.8°F)
Lower scaling point of the voltage
analog input
4 mA corresponds to 0°C
